Predicting hospital readmissions in the Medicare population. 1985

G F Anderson, and E P Steinberg

Using a nationally random sample of Medicare beneficiaries, we developed a multivariate logistic model that identified a series of factors that predict readmission to an acute care hospital within 60 days of discharge. Our regression results show that 10 variables are statistically significant predictors of readmissions, with the patient's disease history and diagnosis among the best predictors. Our results can be used by peer review organizations to evaluate the quality of care provided by different hospitals as well as by physicians and social workers to improve discharge planning.

D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D003953	Diagnosis-Related Groups	A system for classifying patient care by relating common characteristics such as diagnosis, treatment, and age to an expected consumption of hospital resources and length of stay. Its purpose is to provide a framework for specifying case mix and to reduce hospital costs and reimbursements and it forms the cornerstone of the prospective payment system.

It consists of two separate but coordinated programs: hospital insurance (MEDICARE PART A) and supplementary medical insurance (MEDICARE PART B).
